Eric Boullier has stepped down as McLaren's racing director in the midst of the team's recent struggles in Formula One.
Boullier joined McLaren from Lotus in 2014 and was in charge of the sporting aspects of the team during its recent struggles with former engine partner Honda. He had hoped to return the team to the front of the grid with Renault power this year, but a continued failure to perform -- largely due to issues with the car's aerodynamics -- has led to Boullier resigning ahead of the team's home race at Silverstone this weekend.
"I am very proud to have worked with such a brilliant team over the past four years, but I recognise now is the right time for me to step down," Boullier said.
